Hey Elle, I am not an SSC.
I would like to suggest that your stance is a little wide and you could narrow it up an inch or so on each foot.
I watched this video a couple times and I still can't be positive, but it does not appear that you are dragging the bar against your shins. It looks like the bar is just slightly staying in front of you, not in contact with your body.
Something that may help you is simply shifting your weight back towards your heels just prior to the pull. This might help things feel more balanced for you!
